So actually I have been messing with availableatlevel.xml and I found easy way to make any track I want available, at first it looks very big but most of the things are uselses so I made it look like this
[Only registered and activated users can see links. Click Here To Register...] and it works.
I will just change the id to any track of this list >
[Only registered and activated users can see links. Click Here To Register...] <(with the help of textmechanic I got all the links extracted from nfstimes and just copied the track names and ids)
The carclasshash is responsible for making the event either open,a,b,c,d,e, or s event.. so 607077938 means open event.
